Respiratory Anatomy
This structure prevents food from entering the nasal cavity when you swallow.
What is the uvula?
The maximum amount of air a person breathes IN during inspiration.
What is inspiratory reserve volume?
Gas exchange in the respiratory system happens here.
What is in the alveoli?
When the diaphragm and external intercostal muscles contract, this happens to the thoracic cavity.
What is increase in volume?
Infection of the middle ear.
What is otitis media?
This structure prevents food from entering the trachea.
What is the epiglottis?
The normal amount of air that a person breathes in and out with each breath.
What is tidal volume?
In tissues, this gas leaves the blood.
What is oxygen?
When the volume in the thoracic cavity increases, the pressure _______________
What is decreases?
This disease is usually preceded by influenza and symptoms include:
Thick fluid in the alveoli and trachea
What is pneumonia?
These structures keep the trachea open as a hollow tube.
What are C-shaped rings of cartilage?
The maximum amount of air a person breathes OUT during exhalation.
What is expiratory reserve volume?
The bicarbonate ion in blood carries this gas.
What is carbon dioxide?
Raising of the diaphragm and relaxation of the rib cage cause this to happen.
What is expiration?
This is an infection of the primary and secondary bronchi that usually follows a viral upper respiratory infections.
What is acute bronchitis?
These structures equalize the pressure in the middle ear.
What are auditory tubes?
The amount of air that remains in the lungs after a deep exhalation.
What is residual volume?
Hemoglobin carries this gas in blood.
What is oxygen?
This is the process of breathing in.
What is inspiration?
This disease of the bronchi and bronchioles has symptoms of wheezing and breathlessness and the bronchioles can have spasms when exposed to irritants.
What is asthma?
The exterior walls of alveoli are surrounded by these structures.
What are capillary beds?
This is the maximum amount of air that can be moved in and the maximum amount of air that can be moved out during a single breath.
What is vital capacity?
Gas exchange between alveoli and blood.
What is external respiration?
This controls the rhythm of ventilation.
What is the respiratory control center?
Symptoms of this disease include:
Reduced elastic recoil of the lungs
Damaged alveoli walls
Reduced surface area for gas exchange
What is emphysema?
